Submission + - Studies show life may exist without oxygen ( 1

Scientists have found Earth's oldest fossils in Australia and say their microscopic discovery is convincing evidence that cells and bacteria were able to thrive in an oxygen-free world more than 3.4 billion years ago. The finding suggests early life was sulphur-based — living off and metabolizing sulphur rather than oxygen for energy — and supports the idea that similar life forms could exist on other planets where oxygen levels are low or non-existent.

While the (news) title may have been a bit sensationalistic, it's still exciting to know that life could exist in a very different environment that what we previously believed.
